Application filed June 30, 1916. Serial No. 106,876. a

To all whom it may concern: 1 v

Be it known that I, GEORGE W. HAwtEi,

a citizen of the United States, residing at Bridgeport, in'the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Extension- Splints, of which the following is a specification.

My invention relates to splints, and its novelty consists in the construction and arrangement of the parts as will be more-fully pointed out hereinafter. v

In hand-ling fractures, one problem is that the fractured member be so immobilized that-the necessary movement of the other parts of, the p'atients body or of, the bed shall not affect the fractured member. This object is accomplished by the device herein described and claimed by securely immobilizing the fractured member and holding it at all times clear of the bed. r

Another problem solved for the first. time by my device is the quick and rigid securing of the splint to any and every metal bed. My device also is very compact whenclosed and sufficiently light to make, it practical for carrying. v

In the drawings, Figure 1 is a miniature perspective ofthe splint in use; Fig. 2 is a top plan view of the splint showing a foot and leg in dotted outline in use ona bed; Fig. 3 is a vertical section of Fig. 2 along the line 3-3; Fig. 4 is a vertical section along the line 4-4 of Fig. 4. v

In the drawings 5 is a tubular movable frame in which is telescoped an extension frame 6 which has a downturned integral member -7 and the movable frame 5 has a downturned integral rest 8. O11 the downturned member 7 is loosely mounted a rod 9 whichcarries adjustable sleeve members 10 and 11, each of which has a'set screw 12. The sleeve members 10 and 11 are made integral with cross bars 16 and 17 respectively, and they in turn each have two clamp ng pins 14; and 15 made integral therewith. The movable frame 5 is fitted with flexible cross'suspension straps 18 which: are secured to each side of said frame. A foot support 20 is slidably mountedon the movable frame 5 by sleeves 19 which can be rigidly secured to said frame in the position desired, by set screws 23. The movable frame 5 has a cross bar 24 to which is secured chains 21 by means of screws 25, and

to the opposite ends of the chains 25 are permanently secured clips 22. Pins 39 are rigidly mounted in the cross bar 24 adapted to beusedas hooks for the chains 21. A

. single pulley block 26 is riveted to the cross adapted to'hold weights 34 which-are slotted for that purpose at 35. I I The extension splint can be attached to any metal bed restingthe integral rest member.8 on the bed after it has'been madeup, and securing the cross bar 16 by means of the set screw 12 so that asthe clamping pins 14 fit snugly over the top rail36 of the foot of the bed, the desiredpitch is obtained for the splint. The cross bar 17. is then adjusted by means of the set screw 12 so that the, clamping pins 15 fit snuglynnder the lower rail 37 of'the foot of the bed and it is secured-rigidly in that position so that the extension frame 6 is thereby held in afixed rigid position to the foot of the bed. T Then the leg of the patient, for example,is'laid on the suspension straps 18 and the foot support 20 is adjusted in a fixed position by means .of the set screws 23 against the ball of the foot so that it is under pressure and so heldin an upright position. The legis thus held clearof the bed and bed clothes.

To. hold the foot rigidly against the foot support 20 in .anupright position the clips 22 are fastened to'the bandage 38 on each side of the legand the chains 21 are each slipped over oneof the pins 39 so as to keep The desired traction is then-obtained by placing the weights 34 on the weightholder 31 which multiplies the pull on the mov- 1 able frame 5 to which the leg is rigidly secured in accordance with well known laws 105 pulley in the block 27, and thence to the 110 in therblock 27. "The weight holder 31 is I block 26 Where it is fastened to the pin 28. It will be understood that the patient is socured against traction by means of bandages fastened to the traction post of the regular hospital bed, or in any other suitable manner.

Changes may be made in the construction, arrangement and disposition of the several parts of the invention Without in any way departing from the field and scope of the same, and it is meant to include all such in this application wherein only a preferred form has been disclosed.

Having thus fully described my invention, what I claim as n w and desire to secure by Letters Patent, is:

l. in extension splint consisting of an extension frame adapted to be rigidly secured to t 1e bed on which a patient lies, a longitudinally movable frame attached to said extension frame, downwardly turned end rest on the free end of the movable frame, a foot support adjustably mounted on the movable frame, means for securing the foot of a patient in an upright rigid position against said foot support, in combination with an adjustable weight traction suspendcd from the extension frame by a cord running back on itself twice over pulleys on the extension frame, thence secured to the movable frame so as to cause traction thereto. I

2. An extension splint adapted to be readily secured to any metal bed provided Withmeans for securing thelimbto be treated in a fixed ri 'id position to a 'movable frame, in combination With means for exerting the desired traction on the movable frame, consisting of a Weight support to which the desired weight may be added socured by a cord to an extension frame vvhich is rigidly mounted to the foot of a bed, the said cord multiplying the traction according to a fixed la of physics through pulleys on the extension frame and thence secured to the movable frame.

3. An extension splint comprising an extension frame, a movable frame carried by the extension frame, and gravity operable means carried by said frame for moving the movable frametoward the extension frame.

e1. fin extension splint comprising relatively movable members and cooperating gravity operable means carried by said'menihers for moving one of said members toward the other member.

Copies of this patent may be obtained for 5. An extension splint comprising a mov able frame, a foot support, adjustable on said frame, anextension frame for suppor ing the movable frame, and gravity operable tensioning means carried by said frames for movin the movable frame toward the extension frame.

6. An extension splint comprising an extension frame, a movable frame adiustably carried by the extension fran e, gravity operable means secured tosaid frames for moving said movable frame toward the extension frame and means secured to said extension framefor raising or lowering the extension'frame. 1

7. Anextension splint comprising an extension frame, a movable frame carried by the extension frame, means secured to said frames for moving the movable frame, a down-turned member on the extension frame, a rod loosely secured to the downturned member, and cross bars secured to a bed and carried by said rod for adjustably supporting the extension frame.

8. An extension splint comprising an extension frame, a movable frame carried by the extension frame, a foot support carried by the movable frame, gravity operable tensioning means secured to St frames for moving the movable frame toward the :extension frame, and means secured to the movable frame for securing the foot of a patient to the foot support.

9. An extension splint comprising an extension frame, a movable frame carried by the extension frame, means secured to said frames for moving the movable irame on the extension frame, a downturned member on the extension frame and means secured to the doWntu-rned member for adjnstably sup porting the extension frame on a bed.

10. An extension splint comprising an extension frame, a movable frame carried by the extension frame, means secured to said frames for moving the movable frame, a downturned member on the extension frame, a rod loosely secured to the dovvnturned member and means secured to a bed carried by said real for adjust-ably supporting the extension frame.

In testimony whereof I affix mysignature in presence of two. Witnesses.
